AI Technical Summary

Technical Problem

In the existing technology, conveyor belts often run off-track due to uneven material distribution, equipment vibration, and other factors, resulting in problems such as material spillage, edge wear, shortened equipment life, and inconvenience in adjustment.

Method used

A conveyor belt anti-deviation device is adopted, which is mounted on the mounting plate at the center of the bottom surface of the idler frame. The position of the idler frame is adjusted by a single linear translation mechanism and a telescopic mechanism with locking function, avoiding the asynchronous problem of two independent adjustment systems and realizing overall posture adjustment.

Benefits of technology

It simplifies the operation process, improves the accuracy and stability of adjustment, ensures the synchronization and reliability of belt misalignment, extends the service life of equipment, and reduces maintenance frequency and cost.
